Upgrade tree was great! I enjoyed smashing into enemies. The game seemed to pause/hiccup a bit at the end of each countdown. 

obviously the polish is a little challenging but the core ideas are there..  always love me a good upgrade tree! Could see this evolve into a relaxing roguelite.... good work :)

Very nice theme mechanic, clever way of making the countdown matter!

The game has potential, but unfortunately, there’s not much to evaluate other than the gameplay.
